This article aims to provide an in-depth introduction to the HP-IRLED industry, covering its history, technology, applications, market trends, and future prospects.

History of High Power Infrared Light Emitting Diode

The development of HP-IRLED technology dates back to the 1960s when infrared light-emitting diodes (IRLEDs) were first introduced. Initially, IRLEDs were primarily used in remote controls and simple optical communication systems. However, with the advancement of semiconductor technology, the power output of IRLEDs increased significantly, leading to the emergence of HP-IRLEDs in the late 1990s.

Technology of High Power Infrared Light Emitting Diode

HP-IRLEDs are based on the principle of semiconductor junctions, where electrons and holes recombine to emit photons. The key factors affecting the performance of HP-IRLEDs include the material composition, structure, and fabrication process. Common materials used in HP-IRLEDs include gallium arsenide (GaAs), gallium nitride (GaN), and aluminum gallium arsenide (AlGaAs). The structure of HP-IRLEDs typically consists of a p-n junction, with the p-type layer emitting the infrared light. The key to achieving high power output lies in the design of the epitaxial layer, which determines the light-emitting characteristics of the diode. The epitaxial layer is grown on a substrate using techniques such as molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). The fabrication process of HP-IRLEDs involves several steps, including epitaxial growth, doping, and device fabrication. The epitaxial layer is grown on a high-quality substrate, followed by doping to create the p-n junction. The device is then fabricated by bonding the epitaxial layer to a metal contact and encapsulating it in a package to protect it from environmental factors.
